摘　　要：Maize is an important food crop, as well as the irreplaceable feed and industrial materials, having huge market demand in China. Southwestern region of China is the third largest main maize producing zone, and the frequent occurrence of abiotic stress conditions such as drought, heat, cold, wet shaded stress have severely affected the development of maize production, causing low and unstable corn yields, severely restricting the maize industry development in the southwest of China. This paper preliminarily describes the maize resistance to abiotic stresses in southwestem region of China, putting forward the countermeasures and the key research direction in the practice of breeding in order to provide reference for the cultivation of new varieties with high yield and stress resistance, and improving the levels of maize stress resistance breeding in southwestern region of China.玉米是中国的重要粮食作物,也是不可替代的重要饲料原料和工业原料,市场需求量巨大。西南地区是中国第三大玉米主产区,受非生物逆境如干旱、高温、低温、荫湿等胁迫十分频繁,严重影响玉米生产发展,造成玉米单产低而不稳,严重制约西南地区玉米生产发展。该文初步介绍了西南玉米主要非生物气候逆境概况,以及育种实践中玉米抗逆品种选育方向和对策,以期为培育高产抗逆新品种,提高西南地区玉米抗逆育种水平提供参考。
